There are thousands of chemicals in personal care products like lipstick, lotion, shampoo and shaving cream.

Many of those chemicals are linked to breast cancer, either because they are carcinogens, or because they disrupt the body’s hormones. While some of these chemicals are listed on ingredient labels, others are not because they are contaminants, or they are hidden behind the word fragrance.

The cumulative effect of our exposure to these unsafe chemicals — even in small amounts, but with frequent, repeated usage — is a real concern either because the chemicals are carcinogens or because they disrupt the body’s hormones.
